Abstract: |
In this paper, a typical profiled workpiece is taken as an example to investigate and study the causes of common defects such as bubbles, drums, spalling and cracking on thermal protection coating of irregular surfaces. The optimized spraying process and surface treatment methods are used, and environmental temperature and humidity, surface moisture of workpieces are controlled to eliminate the corresponding defect and ensure product quality. |
Key words: thermal protection coating;spraying process;defect control |
